T 0 all whom 'it may concern.

' Be it known that I, lvailrsn SHERRATT, a

subjectof the Kingy oli Great Britain, resi dent ot' (l2 Dixon avenue, in the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, engineer, have invented certain new and useful improve ments in field-'Faults1v of which the followine; is a spccilication.

The invention relates to improvements in acid tanks, as described in the present specification and illustrated in the accompanying drawings that form part ot' the saine.

The invention consists essentially in the novel construction and arrangement of parts whereby the parts are securely held together liquid tight without the use ,of meta-l pieces in the joints.

rlhe object of the invention is to prolongthe lii'e ol a tank l'or containing,r acid by dis-.

pensingr with the usual metal accessories such as nails or bolts, which are soon eaten aivay by the acid and cause leaking and sometimes total collapse oi' the tank.

In the accompanyingl drawings Figure l is avertical transverse section. 3 is a side elevation oi: a part of the tank length with one corner broken into section. Fig. il is a plan lieiv ot a portiono'l" the length ol' the tank and Fig. #l is an enlarged sectional perspective vieiv of one of the joints.

Like numerals ot reference indicate corresponding parte in each figure.

Reierringj to the drawings l the bottom ol the tank comprisimr a plurality o'l thick planks each having` a tapering tongue 2 at one oi? its longitudinal edges and a corresponding tajlcri'ogr groove 3 in, the opposite longitudinal eige, the tongue of one plank snugly fitting; within the groove of the adjacent plank.

lny the perpendicular edges at each side respectively ot said timone and said gro-ore, V-shaped recesses i are arrangml-rco that the recesses ot' one plank coincide with the recesses olf the adjacent plank when 'in po ition, thus leaving a pair of suliistantiaily diamond shaped holes between the a djoininp; edges of said planks one at each side vot the tongue and ,groove and extending the t'ull length of the plank.

In each plank, suitably distanced holes 5 are bored through at intervals from to edge substantially central of the thickness and therefore through both the tongue and. groove.

When the planks comprising the tank bottom vare. assembled a length `of rubber or other suitable resilient material is placed, in ach ot' the holes formed by V-shaped recesses s, said lengths extending from end to eno o the planks. The assembled planks with the holes coinciding.,r are now placed in a cramp and a u'oodenitie rod 6 is threaded in said holes right through the bottom from outside. edge to outside edge, the ends being split and Wedges '7 knocked into said splits. Alifter all otl the tie rods G have been inserted in this Way, which has the e'liect of compressing the rubber lengths 4a and thereby n'mking the joint liquid tight, the cramp is taken oli', as said planks are just as tightly held together by thc tie rods.

'lhe sides i) and ends 10 are composed of I pla ks held together by the tie rods 11 in exactly the same manner as the bottom 1 the joints 12 being of the same character as the joints in. said bottoni, the lower planks of said lsides and ends cach have a depending tong-ue 8, so that really said tongues form a ependingg llango all the `way around the lmundary of the tank. correspondinsr grooves lil boing out into the upper surface ol.2 the bottom l to accommodate said tongues and rubbm.' lengths vinterposed between the nieeting' parts of each side tonp'ue and groove in lhe same manner as that previously describedx V i llooden cross pins 'le extend at intervals through corresjmndinl` holes .in the sides, ends and bottom and through the tie rods ot `said sides, ends and bottom so that said rods have an additional lock above besides thewedges 7.

shown in the drawings the sides 9 eX tend beyond the ends 'lll at l5 and, outside of said ends, braces 16 extend across from side to side. holding said sides together by the dove tailed joints l? ,it is not thought 4that an;v tongue and groote joints are necesd sarjbetween the vertical side edges of the ends and the adjacent inner tace of the sides.r but necessary there may be arranged a joint similar to that between the lower ed "e oilE the sides and enden/'ith the bottom 1. llloiveier all the corners onthe inside of the tank filled up by the triangular corner piece 15%; secured to the adjacent sides, ends and bottom by Wooden dowel pins 19 each of said corner pieces 'i8 preferably having lJ-sha'ped recess in its right angular in which substantially square sec-
